Statement of Problems This study is intended to investigate the effects of heat treatment particularly quenching on the mechanical properties of mild steel especially on its strength using different quenching medium.
The objective of the study is to answer the following questions.
1. What is the strength difference between raw mild steel and to the mild steel that undergo quenching process in the following quenching medium: used engine oil, water, boiler water?
2. Which is the strongest material after it was been quench in used engine oil, water and boiler water?
Significance of the Study The importance of this study is to determine the effect of quenching solutions particularly: used engine oil, water and boiler water to the strength of mild steel. This study also aims to define whether the metal that undergo quenching process is stronger or weaker compared to the same metal but did not undergo quenching

Heat treatment involves the controlled process of heating or cooling the metal at a certain high temperature to bring out its desirable properties. There are different heating techniques that can be applied to change the properties of metal such as annealing, normalizing, tempering, strengthening and quenching. R.Wojes (2017) states that the quenching rate is also a factor to be considered on choosing the quenchant or cooling media. Because the slower the quench rate, the thermodynamic forces has more opportunity to change the microstructure of the materials. That’s the reason why different media is being used depends on the future application of the processed material.
Noor Mazni Ismail, et al. (2016) states that quenching is the process to improve the hardness of metal. Also the best quenching media to acquired maximum hardness is water, it is because water has a fast quenching rate than
The high temperature application of Austenitic Stainless Steel is somewhat limited because at higher temperatures it undergoes a phenomenon called Sensitization. According to Ghosh et al. [1], it refers to the precipitation of carbides and nitrides at the grain boundaries. Precipitation of Chromium rich carbides (Cr23C6) and nitrides at the grain boundaries result when the Austenitic stainless steel is heated and held in the temperature range of 500-8500C (773K-1123K). This precipitation of carbides taking place at the grain boundary is because of their insolubility at these temperature ranges. This leads to Chromium depreciated regions around the grain boundaries. So the change in microstructure is takes place and the regions with low Chromium contents become susceptible to Intergranular Corrosion (IGC) and Intergranular Stress Corrosion Cracking (Alvarez et al.) [1, 2]. Along with carbides and nitrides there is formation of chi phase. The chi phase, which is a stable intermetallic compound, consists of Fe, Cr, and Mo of type M18C. Some studies reveal that sensitization may lead to formation of Martensite. In addition to the altered microstructure, mechanical properties of the Austenitic Stain...

Conduction, Convection, and Radiation Heat transfer is the way heat moves through matter to change the temperature of other objects. There are three types of heat transfers, Conduction, Convection, and Radiation. The first kind of heat transfer, conduction, is heat transferring through direct contact of materials. This would be the same thing as a pan on the stove. The heat from the stove touches the pan directly, therefore making the pan hot.
A wide variety of coating alloys and wrought alloys can be prepared that give the metal greater strength, castability, or resistance to corrosion or high temperatures. Some new alloys can be used as armor plate for tanks, personnel carriers, and other military vehicles.
Hardness test In this study hardness was determined using standard Rockwell A. The tests were conducted at room temperature and under ambient humidity conditions. Hardness testing machine (Avery Denison 6407 150Kgf) was used in the test.
This paper will first discuss the development of the steel industry. Next, it will examine steel, and in the impact it had on the transportation industry. Finally, it will discuss systematic management practices of this time and how they gave birth to the scientific approach that is still in use today.
In this experiment, water is heated with a metal and placed into water at room temperature. The results will be the heat change between the metal and the water at room temperature explaining that energy cannot be created nor destroyed. Introduction: Specific heat is the heat required to raise the temperature of the unit mass of a given substance by a given amount. Specific heat is another physical property of matter.
The precipitation hardening is use the heat treatment process, the heat treatment process of precipitation hardening of the hardness that precipitated nanoscale and microscale intermetallic to avoid reproduce increment of the lattice defects, such as the dislocations is occur. These precipitates is a greatly strengthen of the metal matrix. The metal alloys of hardness may be enhance by a formation of very small and even dispersed particles of a second phase in the origin phase matrix, this will fulfil by a possible heat treatment. As with tempering the between loss of dutility and toughness and resulting increase in strength a balance will be struck when the precipitation hardening. Otherwi...
European countries were not at the same stage of steel production as that of the British. Therefore, their steel productions were not as superior. However, in response to the British, French inventors developed light weight truss known as the Polonceau in 1837. In addition there was the development of forged iron and milled steel. This opened a myriad of opportunities...
A steel is usually defined as an alloy of iron and carbon with the content between a few hundreds of a percent up to about 2 wt%. Other alloying elements can amount in total to about 5 wt% in low-alloy steels and higher in more highly alloyed steels such as tool steels and stainless steels. Steels can exhibit a wide variety of properties depending on composition as well as the phases and microconstituents present, which in turn depend on the heat treatment.
Metals possess many unique fundamental properties that make them an ideal material for use in a diverse range of applications. Many common place things know today are made from metals; bridges, utensils, vehicles of all modes of transport, contain some form of metal or metallic compound. Properties such as high tensile strength, high fracture toughness, malleability and availability are just some of the many advantages associated with metals. Metals, accompanied by their many compounds and alloys, similar properties, high and low corrosion levels, and affects, whether negative or positive, are a grand force to be reckoned with.

Grey cast iron is the most widely used foundry alloy in the world due to its wide range of achievable mechanical properties, good castability, excellent wear resistance and damping properties, high thermal conductivity as well as low cost (20-40% less than steel) (Xu et al., 2005). It is used in such diverse applications as cookware and musical instruments to auto parts and heavy machineries. Microstructure of grey cast iron is characterized by dispersion of graphite flakes in a ferrous matrix. It has been evidently shown that the size, morphology and distribution of graphite flakes greatly affect the physical and mechanical properties of grey cast irons and that these characteristics depend mainly on the chemical composition of the alloy, the foundry practice adapted such as inoculation treatment used and the cooling conditions during solidification (Bartocha et al., 2005; Xu et al., 2005;
Toughness is the ability of a metal to mutilate plastically and to absorb energy in the process before it breaks or fracture. Metals can be heat treated to alter the properties of strength, ductility, toughness, hardness or resistance to corrosion. This can be done by using heat treatment processes which include precipitation strengthening, quenching, annealing and tempering. Annealing and tempering are the most prominent methods for treating metals. A material may become more or less brittle, harder or softer, or stronger or weaker, depending on the treatment used.
