Alloy special for computer hardware manufacturing and machining process thereof

Abstract

The invention discloses an alloy special for computer hardware manufacturing and a machining process thereof. The alloy comprises, by mass, 32.0-40.0% of Cr, 5.0-12.0% of Fe, 0.5-1.0% of Al, 2.0-5.0% of Mo, 6.0-12.0% of Ti, 0.1-0.4% of Mn and 4.0-5.0% of W. According to the alloy special for computer hardware manufacturing and the machining process thereof, the produced high-temperature alloy mother alloy is high in alloy strength, good in abrasion resistance and high-temperature oxidation resistance, small in surface crack quantity in the manufacturing process, good in plasticity and capable of eliminating segregation, so that the produced mother alloy is uniform in structure, low in harmful impurity content in the alloy, small in internal defect quantity and high in yield, materials are saved, and the production cost of the mother alloy is low. An oxidation film on the surface of a raw material can be removed, the vacuum sintering speed is increased, the alloy production efficiency is improved, the oxygen content in the raw material is reduced, and better use prospects are brought.

Description

technical field

[0001] The invention relates to the field of master alloys, in particular to a special alloy for making computer hardware and its processing technology. Background technique

[0002] At present, the production quality of some computer hardware also depends on its raw materials. The quality of raw materials directly determines the quality of the computer itself; master alloy is an alloy material used for casting through refining and precise composition. Also known as casting master alloy. The reason why the master alloy is called "master alloy" is that it has strong genetic properties as the base material for casting, that is, many characteristics of the master alloy (such as carbide distribution, grain size, microscopic mirror structure , even including mechanical properties and many other characteristics that affect the quality of castings) will be inherited to castings after remelting and pouring. The existing widely used master alloy materials include su...
