The balance between the strength and toughness of pure tantalum (Ta) fabricated with selective laser melting (SLM) additive manufacturing is a major challenge due to defect generation affinity for oxygen nitrogen. This study investigated effects energy density post-vacuum annealing on relative microstructure SLMed tantalum. influences impurities were mainly analyzed. results indicated that significantly increased reduction in pore defects oxygen-nitrogen impurities, decreasing from 342 J/mm3...
The improvement and mechanism of the fatigue resistance TC21 high-strength titanium alloy with a high velocity oxygen fuel (HVOF) sprayed WC-17Co coating was investigated. X-ray diffraction (XRD) corresponding stress measurement instrument, surface roughness tester, micro-hardness scanning electron microscope (SEM) were used to determine properties HVOF or without shot peening. behavior determined by using rotating bending testing machine. results revealed that polished had almost same as...
A metallurgical zirconium nitride (ZrN) layer was fabricated using glow metallurgy nitriding with zirconiuming prior treatment of the Ti6Al4V alloy. The microstructure, composition and microhardness corresponding were studied. influence this on fretting wear (FW) fatigue (FF) behavior alloy composite consisted an 8-μm-thick ZrN compound a 50-μm-thick nitrogen-rich Zr–Ti solid solution layer. surface is 1775 HK0.1. gradient in cross-sectional distribution exists plasma improves FW resistance...
A novel electropolishing approach for Ti6Al4V was developed involving a zinc chloride (ZnCl 2 )-urea deep-eutectic polishing system, with current density of 0.6 cm −2 , temperature 90 °C, stirring speed 260 rpm, and time 10 min. The system achieved polished surface 73% reduction in roughness. Compared other processes, the decreased material mass loss rate following titanium alloys, making it suitable additively or conventionally melt-cast fabricated alloys. Using solvent not only improves...
Low wear resistance and high sensitivity to fretting fatigue (FF) damage limit the application of titanium alloys. In order improve its resistance, surface plasma Zirconium (Zr) alloying is a candidate through solution strengthening with property infinite solid [Formula: see text]–Ti text]–Ti. this work, Zr metallurgy technique was used FF Ti6Al4V alloy combined shot peening (SP), which different from treatments modification hardness SP, may explain impacts ductility strength in improving...
Abstract The excellent material properties of tungsten heavy alloy (WHA) make it widely used in the military field. When as killing elements weapons, its dynamic mechanical under detonation loading directly determine damage effect which makes research on behaviors high pressure and strain rate loads such great significance. In this paper, several WHAs with different compositions processes are selected, deformation behavior static explosion test analyzed by combining macro micro study, so to...
Abstract The forming-induced residual stress of metallic parts could cause undesired deformation in the final machining process, especially for thin-walled parts. Therefore, heat treatment is essential to release prior machining. This study investigates change a forged pure iron part annealing and material removal processes. A modified creep constitutive model with consideration microstructure evolution was established describe relaxation annealing. Stress tests were conducted calibrate...
