Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so. NiTi alloys are often used in biomedical applications. The alloys are required to be tailored for suitable operating temperatures. The phase transformation temperatures (PTT) were optimised for shape memory or super-elasticity properties. Micro metal injection moulding (micro-MIM) is a process that can fabricate millimetre-size metal parts with very complex shapes. It is adapted from MIM with significantly smaller injection volume for improved control of dimensions. NiTi alloys with varied Ni contents (45-55 at.%) were fabricated by micro-MIM and sintered at 1150 °C for 2 hours under high vacuum (< 10-4 Pa). X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive x-ray spectroscopy (EDS) and differential scanning calorimeter (DSC) measurements were performed in order to characterise the sintered samples. The results indicated that as Ni contents increased, PTTs were decreased for all transformation temperatures (As, Ap, Af, Ms, Mp and Mf). Moreover, at room temperature (25°C), in the 50Ni-50Ti and 55Ni-45Ti samples, the austenitic B2 NiTi is present, whereas the 45Ni-55Ti sample contains martensitic B19¢ NiTi. 2020-05-20T04:41:47Z 2020-05-20T04:41:47Z 2020 Chiang Mai Journal of Science 47,2 (March 2020), p.297 - 303 2465-3845 https://epg.science.cmu.ac.th/ejournal/dl.php?journal_id=10703 http://cmuir.cmu.ac.th/jspui/handle/6653943832/68605 Eng Faculty of Science, Chiang Mai University
