Relation between microstructure and micromechanical properties on polycrystalline cubic boron nitride (PCBN)

, 2018
Polycrystalline cubic boron nitride (PcBN) is a super-hard material with a multiphase composite character. As it is the case for other super hard materials, information on the smallscale response of PcBN is rather scarce. In this sense, the present work conducts a systematic micro-mechanical study of the mechanical integrity of a cBN embedded in ...

A comparison between single sided friction stir welded and submerged arc welded DH36 steel thin plate [PDF]

, 2012
The adoption of the friction stir welding (FSW) process into the shipbuilding industry is being considered as a medium term issue. Currently the data on friction stir welded mild steels tends to be fragmented, with critical areas being short on specific ...

Polycrystalline {\gamma}-boron: As hard as polycrystalline cubic boron nitride

, 2012
The Vickers hardness of polycrystalline {\gamma}-B was measured using a diamond indentation method. The elastic properties of polycrystalline {\gamma}-B (B=213.9 GPa, G=227.2 GPa, and E=503.3 GPa) were determined using ultrasonic measurement at ambient ...
