Abstract
The invention discloses a kind of chromium manganese nitrogen alloy, be made up of the following material according to weight percent meter: chromium 2-6%, manganese 3-5%, nitrogen 0.8-1.2%, carbon 0.6-2%, silicon 0.3-0.7%, all the other are iron.Beneficial effect of the present invention is: chromium manganese nitrogen alloy provided by the invention, can effectively increase alloy toughness, with liquid nitrogen fast cooling, decrease alloy hole, be more applicable for aerospace field.
Description
Technical field
The present invention relates to alloy field, be specifically related to a kind of chromium manganese nitrogen alloy.
Background technology
Chromium manganese nitrogen alloy, is emerging a kind of alloy in this year, is mainly used in aerospace field, has hardness high, the features such as corrosion-resistant and high-temperature resistant.But the general lacking toughness of chromium manganese nitrogen alloy in the past, in use, easily ruptures.
Summary of the invention
Object of the present invention is exactly for above-mentioned defect of the prior art, provides not easy fracture, the chromium manganese nitrogen alloy that toughness is high.
To achieve these goals, technical scheme provided by the invention is: a kind of chromium manganese nitrogen alloy, be made up of the following material according to weight percent meter: chromium 2-6%, manganese 3-5%, nitrogen 0.8-1.2%, carbon 0.6-2%, silicon 0.3-0.7%, all the other are iron.
Further, above-mentioned a kind of chromium manganese nitrogen alloy, be made up of the following material according to weight percent meter: chromium 4%, manganese 4%, nitrogen 1%, carbon 1.2%, silicon 0.5%, all the other are iron.
Second object of the present invention there is provided the preparation method of above-mentioned chromium manganese nitrogen alloy, is by roll forming after each metallics melting, then with liquid nitrogen cooling.
Beneficial effect of the present invention is: chromium manganese nitrogen alloy provided by the invention, can effectively increase alloy toughness, with liquid nitrogen fast cooling, decrease alloy hole, be more applicable for aerospace field.
