Measurement of in-plane thermal diffusivity of carbon composites by periodic heating method using lock-in thermography (Effects of interface thermal conductance and verification by thermal-numerical model)

Nihon Kikai Gakkai ronbunshu, 2017
Measurement of thermal conductivity for anisotropic material is difficult or troublesome for conventional measurement techniques. Then periodic heating method using lock-in thermography was proposed as a convenient measurement technique.

A Comparative Study of Directed Energy Deposition‐Arc and Casting: Enhancing Mechanical and Thermal Properties of Hot‐Work Tool Steels

steel research international, EarlyView.
The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.
