High-entropy alloys have attracted tremendous research interest in recent years because of their special functional properties. However, the investigations on high-entropy with thermal- and magnetic-field-induced magnetostructural transformation are still lacking. In this work, we provide a basic strategy to design six-component MnFeCoNiGeSi system, exhibiting low-hysteresis between ferromagnetic orthorhombic paramagnetic hexagonal phases. An increase configurational entropy is helpful make...
Being a crucial research frontier, high-entropy alloys advance traditional materials in mechanical properties under various conditions. Nonetheless, other functions, like magnetic, electrical, and optical properties, of are still deficient. This paper presents system exhibiting large barocaloric effect. Experimental results confirm that equiatomic FeMnCoNiGeSi CrMnCoNiGeSi solid-solutions with hexagonal orthorhombic structures at room temperature, respectively. Further tuning Fe/Cr ratio...
By using Deform-3D software, the necking extrusion forming processes of integer trailer axle with two different heating means which are Uniform Heating (UH) method and Partly (PH) temperature gradient simulated. The influence deformation parameters such as friction factor, coefficient, distribution work-piece on material flow features, stress strain field, loading force process analyzed in detail. According to numerical simulation results, PH can improve during tube process.
Palladium coated Copper (PCC) bonding wire is a popular low cost alternative for Gold wire. The quality of an innovative Pd coating technique on Cu (Direct PCC) evaluated by comparing free air ball (FAB) deformability and stitch bond strength to those applied commercial which either thermally treated or as-delivered. FABs 40 μm diameter are produced in two different shielding using 20 direct PCC (DPCC) bare wires. deformed under force 400 mN. DPCC FAB made forming gas deforms 0.60 1.92% more...
By using finite element method, the causes of forming defects such as shortage material and punching recess thickened during drill pipe joints forging were studied some solutions put forward. According to numerical simulation results, one defect named caused by metal irregular flow at bottom necking die, which can be resolved reducing die forming-angle increasing width punch. On condition with D 0 / d ≤2.6 (D0 refers outer diameter, inner diameter), process completed one-step backward...
NiCrBSi coating was prepared on the surface of 45 steel by CO 2 laser. The microstructure clad layer characterized SEM、EDS and XRD. microhardness wear resistance laser examined. results show that can be achieved under technical processing parameters good metallurgical bonding is formed between substrate. uniform, continuous free pores cracks. mainly composed g-Ni, Ni 3 B, CrB Cr 23 C 6 particles.
