Abstract

The invention discloses a novel light weight alloy which is a novel titanium alloy. The alloy comprises the following main elements in percentage by weight: 0.1-0.4% of carbon, 0.05-0.1% of manganese, 0.5-1% of silicon, 2-2.5% of aluminum, 5-10% of nickel, 0.3-0.7% of molybdenum, 10-15% of iron, 0.02-0.06% of boron, and the balance of titanium and inevitable impurities. The novel titanium alloy is prepared by mixing the raw material components, pressing the mixture into a preform and sintering the preform at a high temperature. Through the manner, the alloy uses the design of cheap raw materials, the cost is low, and the alloy has a good mechanical property and a good processing property.

Description

A kind of novel light alloy

Technical field

The present invention relates to metal alloy compositions field, particularly relate to a kind of novel light alloy.

Background technology

Titanium alloy has the advantages such as quality is light, intensity is high, good corrosion resistance, utilize titanium alloy to manufacture engine part and have a lot of benefit, the density of titanium alloy is low, the inertial-mass of moving parts can be reduced, titanium valve spring can increase free vibration simultaneously, weaken the chatter of vehicle body, improve rotating speed and the output rating of engine.

Although titanium alloy component have so superior performance, but generally apply apart from titanium and titanium alloys and also have very large distance in the automotive industry, main reason is its high cost, therefore, be badly in need of exploitation a kind of low cost, high performance new titanium alloy, extensively can enter automobile and other related industrial fields to make titanium alloy.

Summary of the invention

The technical problem that the present invention mainly solves is to provide a kind of novel light alloy, and use the alloy designs of inexpensive raw material, cost is low, has good mechanical property and processing characteristics.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: providing a kind of novel light alloy, is new titanium alloy, and its principal element and mass percent are: carbon: 0.1-0.4%; Manganese: 0.05-0.1%; Silicon: 0.5-1%; Aluminium: 2-2.5%; Nickel: 5-10%; Molybdenum: 0.3-0.7%; Iron: 10-15%; Boron: 0.02-0.06%; All the other are titanium and inevitable impurity; Described new titanium alloy by above-mentioned each feed composition through mixing, be pressed into base and high fever and sinter and form.

In a preferred embodiment of the present invention, the relative density of described new titanium alloy is 98%.

In a preferred embodiment of the present invention, described titanium content is not less than 75%.

In a preferred embodiment of the present invention, described inevitable foreign matter content is not higher than 0.02%

The invention has the beneficial effects as follows: novel light alloy of the present invention, be a kind of new titanium alloy adopting the cheap element such as iron, nickel, aluminium to replace expensive alloy element to make, cost is low, has good mechanical property and processing characteristics.
