such as plasma-spraying, high-velocity oxy-fuel spraying and detonation gun methods [1]. Bell and Sun (2002) discussed that a low temperature plasma carburizing technique has recently been developed to engineer the surfaces of austenitic stainless steels to achieve combined improvement in…

Performance Evaluation: NIPPON STEEL & SUMITOMO METAL CORPORATION (NSSMC) is a joint venture based in Tokyo (Japan) and as the name implies, it produces steel in high capacity. The company was originally known as Nippon Steel Corp but after the merger with Sumitomo Metal in October 1st of 2012, was later changed to “Nippon Steel & Sumitomo Metal Corporation”. In 2012, the company ranked the world second largest steel producer after the union. This report will analyze in deep the company…

3.3.3 Selection of Die Angles The split die was designed for the ease of assembly for fabrication. AISI 52100 steel was selected as the material for the die fabrication. The entry part of the die is 12 mm and has 120 mm length. The profile of the die is also shown in the solid works software. The angle of the die is 90 is maintained, the slope radius is 20 mm. the Figure.3.1 & Figure. 3.2. illustrate the split die design and solid works model of the split die. Figure. 3.1 : Split die…

Cast iron cookware is not a thing of the past; it is actually an item that is used by many cooks and homemakers on a daily basis. The cookware that is made of cast iron has many benefits. It conducts heat very well; it heats the food evenly and thoroughly and can even be resistant to foods sticking to it. It is only resistant to foods sticking if it has been seasoned well and not allowed to become unseasoned. If you have never used this type of cookware, you might be pleasantly surprised what…

The primary focus of the lab was to understand the process and effects of cold working and annealing compared to a baseline sample. Cold working is a form of strain hardening in which metals are worked through the use of applied pressure, thereby making the metal harder[]. This applied pressure led to harder material by creating linear defects known as dislocations. The specific type of dislocation that occurred in this lab was an edge dislocation where an extra plane of atoms was inserted into…

All metal manufacturing includes a solidification process. The metal is either atomised to a powder, or it is cast. There is several casting methods used today. Many of the methods use the mould only once, for example sand mould casting, the lost-wax method and precision casting. For larger quantities of liquid metal, there are basically two methods: ingot casting and continuous casting. Ingot casting normally uses a permanent mould made by cast iron isolated by ceramic material. There are…

1. Introduction 1.1 Lubrication Friction is caused during machining operation at tool and chip interface. This produces the heat which affects the machining performance in terms of surface finish, dimensional accuracy, tool life and machining cost. To reduce the heat different techniques have been utilized. Earlier, during industrial revolution water was utilized as a coolant but it caused corrosion [1]. With the development of technology different cooling and lubrication techniques have come…
