ASTM B294 - Standard Test Method for Hardness Testing of Cemented Carbides
November 1, 2017 - ASTM

This test method covers the hardness testing of cemented carbides by use of a Rockwell hardness tester performing tests in the Rockwell HRA scale (regular scale, diamond indenter, 10 kgf (98.07 N) preliminary test force, and 60 kgf (588.4 N) total test force in the range of Rockwell 80 HRA...

Nanophononics: Thermal Generation, Transport, and Conversion at the Nanoscale
November 16, 2017 - CRC

Heat in most semiconductor materials, including the traditional group IV elements (Si, Ge, diamond), III-V compounds (GaAs, wide-bandgap GaN), and carbon allotropes (graphene, CNTs), as well as emerging new materials like transition metal dichalcogenides (TMDCs), is stored and transported by...

AGMA 16FTM14 - Impact of Surface Condition and Lubricant on Effective Gear Tooth Friction Coefficient
September 1, 2016 - AGMA

The actual power loss due to friction in a gear pair is of significant interest to the transmission community. This loss impacts fuel efficiency on almost every form of transportation. In aircraft applications, this loss converts to heat, which must be removed using cooling equipment, inherently...
