The mechanical properties and the microstructure were experimentally examined for the Sn3mass% Ag solders with 0, 3, and 6mass% of Bi connecting two Cu substrates or two (SnPb)/Ni/Cu substrates.
Oct 05, 2018 · Thermo-mechanical treatments allowed to modify the microstructure in the size and shape of the On the bainitic and martensitic phase transformation transformation behavior, the mechanical properties and the dimensional stability, is indispensable. In particular, the austenitization treatment has a strong influence on the subsequent phase transformation
Phase transformation, microstructure and mechanical property of Ni 50-x/2 Ti 50-x/2 Al x (x=1, 2, 3 and 4 at.%) alloys have been investigated by electrical resistance (ER) measurement, scanning electron microscope (SEM), X ray diffraction (XRD) and tensile tests. The results show that a two-step phase transformation occurs from parent phase to R phase and subsequently to martensite upon Phase Transformations and Mechanical Properties of the Request PDF Phase Transformations and Mechanical Properties of the Nitinol Alloy with Shape Memory We study the Ni55.8Ti44.2 alloy in the form of rods
Jun 01, 2014 · Phase transformation behavior of the quasicrystalline icosahedral phase (I-phase) and mechanical properties in a Ti 41.5 Zr 41.5 Ni 17 alloy have been investigated using suction-casted bulk samples with various sample sizes ( = 2, 3 and 5 mm). For 2 and 3 mm diameter rod samples, micrometer size dendritic -(Ti,Zr) phases are precipitated in the matrix and continuously I-phases are Phase transformation behavior and mechanical properties of Introduction:The bending and torsional properties of thermomechanically treated K3XF (SybronEndo, Orange, CA) nickel-titanium instruments in relation to their phase transformation behavior were evaluated. Methods:NiTi instruments K3 (SybronEndo) and K3XF, both in sizes 25/.04 and 40/.04, were examined by differential scanning calorimetry and X-ray diffraction.
Feb 15, 2021 · This study examined the fundamental mechanisms of the effects of SPS conditions on microstructure evolution, phase transformation, and mechanical properties. For this purpose, a lunar regolith simulant (FJS-1) was selected and sintered for a total of 16 cases based on four primary SPS testing parameters:temperature, applied external pressure, dwell time, and heating rate. Teaching Metallurgy - Phase Transformations and Complex The patterns in which atoms are arranged in the solid state determine properties. These arrangements can be manipulated by altering parameters such as the chemical composition, temperature and magnetic field. A phase transformation is a change in the pattern of atoms. We work on phase transformations and the relationship between structure and properties.
The relationship between microstructure and mechanical properties was addressed at several levels. At the local scale, the nano-indentation technique was coupled with SPM imaging and EBSD to measure the hardness and elastic modulus of each phase, taking into account phase
