Research on heat treatment process of 6016 aluminum alloy

Zhang Junping,Jin Qingsheng and Ma Mingtu

Strategic Study of CAE 2014, Volume 16, Issue 1, Pages 103-107

Abstract:

Research on heat treatment process of 6016 aluminum alloy has been carried out by means of hardnessThe hardness of alloy initially decreases and then increases with pre- aging time increase when pre-aging.The higher the temperature of pre- aging，the bigger the decrease value of hardness will be.;20 min solution treatment + 120 ℃×10 min preaging.

the characterization of pore structures and permeability of diesel contaminated clays under different aging

Frontiers of Structural and Civil Engineering Pages 1264-1280 doi: 10.1007/s11709-023-0921-x

Abstract: to characterize the pore structures and investigate the permeability characteristics of clay after agingThe results of the MIP tests showed that aging leads to reductions in porosity and average diameter,The XRμCT analysis yielded consistent results; it showed that aging renders pores more spherical andMechanistic analysis showed that aging weakens interparticle cohesion; this causes large agglomeratesBoth aging and diesel content can weaken the permeation characteristics of soil.
