Reactive-Sinter-Processing and Attractive Mechanical Properties of Bulk and Nanostructured Titanium Boride

An approach to synthesize bulk nanostructured titanium boride (TiB) ceramic material having a whisker‐like microstructure with a very attractive combination of mechanical properties is presented. The material is made of a three‐dimensional network of high aspect ratio TiB whiskers that are created i...

Description
Summary:An approach to synthesize bulk nanostructured titanium boride (TiB) ceramic material having a whisker‐like microstructure with a very attractive combination of mechanical properties is presented. The material is made of a three‐dimensional network of high aspect ratio TiB whiskers that are created in situ during reaction sintering of micron‐sized component powders at pressures of 15–20 MPa and at relatively low temperatures (
