    Production of Ni-Ti alloys is mostly done by vacuum melting, whilst various melting procedures are used (electron beam melting, arc melting (Ma & Wu, ) and (), high frequency vacuum melting in a graphite crucible or (Tsai et al., ), plasma melting, etc.).When Ni-Ti alloys are melted, there can be unfavourable effects, especially of gases such as nitrogen or by: It is shown that cast targets of highly pure refractory metals like W, Mo, Ti, Ta, Co, etc. and their compounds can be produced by means of a set of vacuum-metallurgical techniques—by vacuum high-frequency levitation, EB floating zone melting, EB melting, and electric arc vacuum melting as well as chemical purifying by ion exchange and halides. The cast refractory metal targets are extremely Cited by: 1.

The as-cast MgLi-1Zn alloy was hot rolled at different temperatures with the reduction of 50%, followed by cold rolling with the reduction of 80%. The effects of the hot rolling temperature on the microstructure and mechanical properties of the final specimens were investigated. The results show that the higher rolling temperature brings about a more homogeneous microstructure, which is Author: Qiang Wu, Kunning Fu, Ruizhi Wu, Jinghuai Zhang, Legan Hou, Milin Zhang.

Finally, the design of new equipment is described. At this time, it is uncertain whether hot- rolling metals in vacuum will gain commercial acceptance in the future. Early investigations of vacuum rolling established that oxidation could be essentially prevented and that metals which cracked during air rolling could be successfully rolled in vacuum.

Meaning of Rolling 2. Process of Rolling 3. Load and Power Requirement 5. The process of shaping metals into semi-finished or finished forms by passing between rollers is called rolling. Rolling is the most widely used metal forming process.

It is employed to convert metal ingots to simple. For hot rolling of metals they are first cast into ingot moulds of suitable form (rectangular, square or round).

The size of ingot depends upon the metal to be cast and the end-product desired. For hot rolling, the ingot is removed from the mould after solidification when it is hot and placed in the gas fired furnace called soaking pits. cessing. Metal forming is the main method of making metal products and semi-finished products.

More than 90% of smelt-ed metal is processed by different methods of metal forming. Plastic properties of metals are used during the process of metal forming.

Both hot rolling and cold rolling are used to create sheet metal. However, cold rolling produces thinner sheets. Hot rolling is also commonly used to create railroad rails, and cold rolling is often used to make beverage cans. This was only a caveat of rolling info highlighting. This volume compiles information from physics, metallurgy, and mechanical and electrical engineering to epitomize the fundamental characteristics of flat rolling steel.

Rolling is a metal forming process in which metal stock is passed through a pair of rolls. Rolling is classified according to the temperature of the metal rolled.

Steelmaking is the second step in producing steel from iron ore. There are three primar. Hot & Cold Working and the Rolling Process. The hardness of the material cannot be controlled after hot rolling and it is a function of chemical composition and the rate of cooling after rolling.

The hardness is generally lower than that of cold rolling and the required deformation energy is lesser as well. Cold rolled products consist. In sheet metal forming practice, we distinguish five basic modes of deformation: • STRETCHING: The material is expanded in both directions.

This mode of deformation is found mostly on smooth bottoms of shallow parts and in hydroforming processes. • DRAWING: This mode is typical the material flow from the flange towards theFile Size: 1MB.
