Abstract
A hard, tough, strong ceramic body is formed by hot pressing a mixture of a powdered metal and a powdered metal diboride. The metal employed is zirconium, titanium or hafnium and the diboride is the diboride of a different member of the same group of zirconium, titanium or hafnium to form a ternary composition. During hot pressing at temperatures above about 2,000.degree.F., a substantial proportion of acicular ternary monoboride is formed.
Claims9
A tough, hard, hot pressed shaped body containing boron and at least two of the three elements, titanium, zirconium, hafnium, hot pressed from a mixture of powdered metal and a powdered diboride to form substantial quantities of a ternary monoboride of said elements and having a percentage composition corresponding to the formula
- (M1, M2).sub.x B.sub.2
- where M1 is titanium, zirconium or hafnium and M2 is a different metal of the group of titanium, zirconium and hafnium, and where x is between about 1.25 and about 2.5.
A tough, hard, hot pressed shaped body containing boron, titanium and zirconium hot pressed from a mixture of metal and diboride to form substantial quantities of titanium-zirconium monoboride and having a percentage composition corresponding to the formula
- (Ti, Zr).sub.x B.sub.2
- where x is is between about 1.25 and about 2.5.
A tough, hard, hot pressed shaped body having a composition corresponding approximately to a ternary monoboride of titanium and zirconium and having approximately equal atomic proportions of titanium and zirconium.
A method of making a hard, tough, shaped body comprising hot pressing at a temperature at least about 2000.degree.F. a uniform mixture of powdered metal and powdered metal diboride where the diboride is selected from the group consisting of titanium diboride, zirconium diboride, hafnium diboride and mixtures thereof and the powdered metal is a different metal selected from titanium, zirconium, hafnium and mixtures thereof, said method forming substantial quantities of a ternary monoboride from said powdered metal and said diboride.
A method of making a strong, tough, hard, shaped ceramic body comprising uniformly mixing zirconium diboride powder and about 10% to about 30% by weight of titanium metal powder and hot pressing said mixture at about 3,000 pounds per square inch at a temperature of at least about 2,500.degree.F., to produce a ceramic body containing substantial quantities of acicular zirconium titanium monoboride.
