Advanced Engineering Materials, EarlyView.This study explores a process chain to produce dispersoid‐strengthened CuCr1Zr for applications requiring high strength and conductivity. Using gas‐atomized powder and copper‐plated alumina nanoparticles, additive manufacturing is performed via powder bed based additive manufacturing with green and red lasers, followed by heat treatment.

Dynamic Hardness Tester and Cure Meter [PDF]
, 1993 The Shore hardness tester is used extensively throughout industry to determine the static modulus of materials. The new apparatus described here extends the capability of an indentor-type tester into the dynamic regime, and provides a measurement of the ...

Response of A356 to warm rotary forming and subsequent T6 heat treatment
, 2014 The through-process microstructural effects in A356 subjected to rotary forming at elevated temperatures have been investigated. Macro and micro-hardness testing have been used extensively to track changes in the material from the as-cast state to as ...

Experimental study on elements diffusion of carbide tool rake face in turning stainless steel
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018 Affected by high temperature and pressure during the process of cutting stainless steel, the affinity element diffusion of tool-chips leads to the appearance of adhesion on the rake face, which eventually results in adhesion failure of the tool.

Advanced Engineering Materials, EarlyView.This perspective article explores an innovative powder metallurgical approach to producing high‐nitrogen steels by utilizing a mixture of stainless steel and Si3N4. This mixture undergoes hot isostatic pressing followed by direct quenching. The article also examines adapting this method to laser powder bed fusion (PBF‐LB/M) to overcome nitrogen ...

NP-hardness of hypercube 2-segmentation [PDF]
, 2014 The hypercube 2-segmentation problem is a certain biclustering problem that was previously claimed to be NP-hard, but for which there does not appear to be a publicly available proof of NP-hardness.
