...Liang Wang; Sergio Felicelli A three-dimensional finite element model was developed to predict the temperature distribution and phase transformation in deposited stainless steel 410 (SS410) during the Laser Engineered Net Shaping (LENS™) rapid fabrication process. The development of the model...

... understanding of the transport phenomena and heat transfer analysis is essential to predict the thermally induced stresses in the deposited materials. A complete model that provides a quantitative relationship between process parameters, temperature history, phase transformation kinetics, and the thermal...

...Yajun Fan; Zhishang Yang; Peng Cheng; Keith Egland; Lawrence Yao In laser forming, phase transformations in the heat affected zone take place under steep cooling rates and temperature gradients, and have a significant affect on the laser forming process and final mechanical properties of products...

... that this type of SiC wheel could grind fully and partially stabilized zirconia (PSZ) very effectively. X-ray diffraction was used to analyze the percentage of monoclinic phase in the PSZ base material, ground surface, and debris. As expected, due to the stress- and temperature-induced phase transformation...

... are formed. This is the evidence of phase transformation, which explains the flank wear data observed in [9]. In addition, phase transformation explains the scatter in flank wear data in the literature because the onset of phase transformation depends on the exact composition of the work materials as well...
