Strength And Ductility

Hot ductility testing is used to evaluate the liquation cracking susceptibility of high Strength aluminum alloy 2219, the fracture surface of hot ductility samples are inspected by SEM, the results showed that the melting point of α(Al)-CuAl2 divorced eutectic is higher than that of α(Al)- CuAl2 eutectic. The α(Al)- CuAl2 divorced eutectic is prior to melting during heating process and solidification during cooling process, so the BTR of Al-Cu alloy 2219 is narrow. The low liquation cracking susceptible and good weldability of Al-Cu alloy 2219 due to the rapidly recover the strength and ductility in elevated temperature which caused by the α(Al)-CuAl2 divorced eutectic solidification during cooling process.

Microstructural Control

Extensive studies to develop high strength linepipes with higher deformability have been conducted. One of the key technologies for improving deformability is dual-phase microstructural control. Steel plate with ferrite-bainite microstructure can be obtained by applying Thermo-mechanical controlled processing, TMCP, made up with controlled rolling and accelerated cooling process. Low carbon-boron free steels were used to enable the ferrite formation during cooling after controlled rolling, and the accelerated cooling process with ultimate cooling rate enabled to achieve high strength of up to X120 grade. On-line heating process by induction device was also applied subsequently after accelerated cooling in order to improve Charpy energy of the base material and homogeneity of material properties in the plate. Trial production of X120 high deformability linepipe was also conducted by applying dual-phase microstructural control. Microstructural and mechanical properties of X120 linepipe are introduced in this paper.

High Strength Aluminum Alloys

Abstract Aluminum alloys are attractive for a number of applications due to their high specific strength, and developing new compositions is a major goal in the structural materials community. Here, we investigate the Al-Zn-Mg-Cu alloy system (7xxx series) by machine learning-based composition and process optimization. The discovered optimized alloy is compositionally lean with a high ultimate tensile strength of 952 MPa and 6.3% elongation following a cost-effective processing route. We find that the Al8Cu4Y phase in wrought 7xxx-T6 alloys exists in the form of a nanoscale network structure along sub-grain boundaries besides the common irregular-shaped particles. Our study demonstrates the feasibility of using machine learning to search for 7xxx alloys with good mechanical performance.
