“…According to the temperature distribution shown in the equations (8) and (9), it is found that the temperature of the sample center is about 3.8 ± 2 K, 12.6 ± 2 K, and 26.6 ± 2 K higher than that of the sample edge under high rate of 20 K/min, 60 K/min, and 140 K/min, respectively. This means the temperature of sample center (the actual sintering temperature) is larger than that of measured temperature by the thermocouple.…”

“…Afterward, various conventional surface‐modification technologies are introduced because these technologies had played a decisive role in further utilizations of Ti and Ti alloys in the past. Third, many new preparation technologies of Ti and Ti alloys, such as additive manufacturing and powder metallurgy (for porous structures) were developed in the recent decades. Many Ti products may have complex shapes.…”

Thanks to a considerable number of fascinating properties, titanium (Ti) and Ti alloys play important roles in a variety of industrial sectors. However, Ti and Ti alloys could not satisfy all industrial requirements; the degradation of Ti and Ti alloys always commences on their surfaces in service, which declines the performances of Ti workpieces. Therefore, with aim to further improve their mechanical, corrosion and biological properties, surface modification is often required for Ti and Ti alloys. This article reviews the technologies and recent developments of surface-modification methods with respect to Ti and Ti alloys, including mechanical, physical, chemical, and biochemical technologies. Conventional methods have limited improvement in the properties and/or restriction on the geometry of workpieces. Therefore, many advanced surfacemodification technologies have emerged in recent decades. New methods make Ti and Ti alloys have better performance and extended applications. With requirement of high surface properties in future. Understanding the mechanism in various surface-modification methods, combining the advantages of current technologies and developing new coating materials with high performance are required urgently. As such, incorporation of different surface-modification technologies with high-performance modified layers may be the mainstream of surface modifications for Ti and Ti alloys. . His current research interests focus on the metal additive manufacturing (e.g., selective laser melting, electron beam melting), titanium alloys and composites, and processing-microstructureproperties in high-performance materials.

“…Ultrafine-grained iron alloys and stainless steels with high strength were produced by Libardi et al and Gaël Marnier et al via SPS of ball milled powders [40,45]. Also, bulk multimodal-grained iron powder materials with high plasticity have been fabricated by SPS in another study conducted by Yang et al [46]. Despite it has not been reported in the literature yet, the above-mentioned technical facts and relevant studies have provided a promising prospect on preparing bulk Fe-N alloys via SPS of synthesized ultra-fine Fe-N powders.…”
