Given the infinite diversity of microstructural inhomogeneity, variation in spatial distribution local strain could be infinite. However, this study finds that statistical universally follows a lognormal irrespective phase content and deformation mechanism. Moreover, universal law is proved conditional upon macroscopic homogeneity on window scale, equivalent to equality between macrostrain calculated from displacements at corners average strain. The discovery suggests existence minimum...
Multiple steel grades used in a car body were unified chemistry to revolutionize automotive manufacturing and recycling.
The effective dispersion and distribution control of reinforcements are crucial factors that influence the mechanical properties metal matrix composites. Here, we propose a strategy to disperse carbon nanotubes in aluminum composites using Ti "nano-grinding balls" as an auxiliary method, achieving interfacial/intragranular nano-reinforcements. Reinforcements with different dimensions can exert strengthening effects induce high density stacking faults (SFs) by generating high-stress regions...
Abstract Medium-Mn transformation-induced plasticity steels have great potential to significantly reduce vehicle weight and improve fuel economy due their outstanding combination of high strength excellent ductility. One bottleneck the application is poor weldability resulting from Mn contents. In this paper, three resistance spot welding set-ups, including no shim, an interstitial-free steel shim at faying interface (shim-in) shims against electrodes (shim-out), were incorporated...
Al-Si-coated boron-alloyed steels are the most widely used press-hardened (PHSs), which offers good oxidation resistance during hot forming due to presence of near eutectic Al-Si coating. In this study, a recently developed novel un-coated resistant PHS, called coating-free PHS (CF-PHS), is introduced as an alternative commercial coated PHSs. With tailored additions Cr, Mn, and Si, new steel demonstrates superior with sub-micron oxide layer after conventional stamping process. Hence, it does...
Identifying the fracture resistance capabilities and gaining a deeper understanding of controlling damage mechanisms are important to development press-hardened steels (PHS) for automotive applications. In this study, properties novel PHS alloyed with Cr Si (CrSi-PHS) were assessed by using uniaxial tensile double-edge notched (DENT) tests. Under tension, is characterized strain work fracture, CrSi-PHS presents desirable compromise strength when comparing other grades advance high-strength...
In this work, solitary wave solutions of particle mechanical metamaterials are studied, in which the mass-in-mass structure with local resonators is considered. The Hertzian contact theory used to describe adjacent particles a precompressed granular chain. governing equations decoupled, and expressions bright, dark, peaked waves derived, respectively. According results, both velocity prestress can affect propagation waves. amplitudes bright smaller when larger applied, different from dark...
