Thermal contact resistance in a non-ideal joint [PDF]
, 1971 The contact conductance at an interface can be determined by knowing the material and surface properties and the interfacial pressure distribution. This pressure distribution can be influenced strongly by the roughness of the mating surfaces but until ...

Advanced Engineering Materials, EarlyView.Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Nonmonotonic Aging and Memory in a Frictional Interface
, 2017 We measure the static frictional resistance and the real area of contact between two solid blocks subjected to a normal load. We show that following a two-step change in the normal load the system exhibits nonmonotonic aging and memory effects, two ...

Advanced Engineering Materials, EarlyView.This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Thermal Resistance Analysis and Numerical Optimization of Mechanical Expanded Tube-to-Fin Joints
Zhileng xuebao, 2020 The finite element simulation method was used to obtain the distribution of contact stress between the fin and the base pipe. It is proposed that the overall contact stress is not just the average value of the node contact stress, and a more reasonable ...
