Abstract
The present disclosure provides compositions comprising iron, about 0.01 to about 0.4% w/w of manganese; about 1.3 to about 1.9% w/w of chromium; about 0.1% w/w or less of nickel; about 1.2 to about 1.7% w/w of molybdenum; about 0.01 to about 0.4% w/w of niobium; about 0.01 to about 0.4% w/w of vanadium; about 1.5 to about 2% w/w of silicon; and about 0.01 to about 0.20% w/w of carbon. The present disclosure also provides methods of preparing a metal powder, comprising atomizing a composition described herein and methods of preparing a metal object, comprising subjecting metal powder described herein to metal binder jetting.
Claims26
A method of preparing a sintered metal object, comprising:
- (i) atomizing a composition to form a metal powder, wherein the composition comprises iron and:
- about 0.01 to about 0.4% w/w of manganese;
- about 1.3 to about 1.9% w/w of chromium;
- about 0.1% w/w or less of nickel;
- about 1.2 to about 1.7% w/w of molybdenum;
- about 0.01 to about 0.4% w/w of niobium;
- about 0.01 to about 0.4% w/w of vanadium;
- about 1.5 to about 2% w/w of silicon;
- and
- about 0.01 to about 0.20% w/w of carbon;
- (ii) depositing two or more layers of the metal powder to form a component;
- and
- (iii) sintering the component to provide the sintered metal object.
