Sn-12wt.% Bi (alloy A) and Sn-12wt.% Bi-1wt.%Sb (alloy B) solder alloys homogenized at 463K for 24h were annealed for 2h at 443K. From both alloys a group of samples was slowly cooled to room temperature with a cooling rate of 1.2x10-2 K/s. A second group of samples was rapidly quenched in cold water (273K). Stress-strain, σ−ε, tests performed in the temperature range from (333-413) K in steps of 10 K, showed a temperature dependence of the hardening behaviour with minimum at 353K followed by a peak at 363K above which showed continuous decrease. The softening behaviour increased to 353K then showed minimum at 363K followed by continuous increase at higher temperatures for both alloys. In the low temperature range the softening coefficient, α, increased with Sb addition and its values were higher for the slowly cooled samples than the quenched samples. The intrinsic hardness at 0K, H o, was higher for the tertiary and quenched samples all over the tested temperature range. In the high temperature range, α showed a constant value of .02, Ho showed different values at 0K due to the different initial states of the tested samples. Increasing the temperature and Sb addition lead to more softening. The activation energy for the annealed and quenched samples of both alloys were found to be 16.72 and 19.144 kJ/mol for the low and high temperature regions, respectively.

The deterioration of materials during industrial application poses a serious threat to the materials structural integrity. A material's susceptibility to wear and surface damage can be reduced by alteration of its surface chemistry, morphology and crystal structure. Therefore, modification of surface properties plays an important role in optimizing a material's performance for a given application. Modern industrial applications require materials with special surface properties such as high hardness, wear and corrosion resistance, therefore materials engineers are vital to regularly examine how the microstructure of a material can be altered. Aluminium-based alloys have a wide application in the automotive, domestic and aerospace industries due to their excellent mechanical properties such as good weldability, sound castability and outstanding resistance to corrosion. The purpose of this research is to enhance inherent properties of the materials to create new products or improve on existing ones. The most effective engineering solution to prevent or minimize such surface region of a component is done by fibre lasers. It was concluded that Hypereutectic Al-Si alloys having transition metals are exceptional materials due to their specific properties. The addition of Cu, Fe, Cr, Si, Mg and Ni to Al-based alloys can improve the mechanical properties at both ambient and elevated temperatures.

“…As a result, tin is frequently used to prevent seizure in bearings when the system runs out of lubrication. Tin is also known for its anti-welding characteristics with iron, thus reduces the possibility of adhesive wear [26,27]. During FSP, the homogeneous distribution of the reinforced particles and formation of a defect-free composite surface depends on the material flow [9,10].…”

Tribological characteristics of friction stir processed graphite and tin/LM24 surface composites

Friction stir processing (FSP) is an emerging solid-state technique for preparing surface composites using various reinforcements. Ceramics and metallic particles are easily reinforced in a matrix by this technique. Surface composites made from an LM24 alloy reinforced with graphite and tin, with good wettability and material flow owing to the low melting point of tin, were fabricated by FSP at two rotational speeds of 1,400 and 1,000 rpm. Despite its low hardness, the graphite/LM24 surface composite fabricated at a higher rotational speed of 1,400 rpm exhibited better wear resistance. However, its frictional behavior was not significantly affected by the reinforcement. The fabricated surface composites with graphite and tin reinforcement as well as graphite-only reinforcement exhibited contradicting behaviors under sliding wear conditions. The post wear analysis indicated that abrasion, adhesion, layer formation, and delamination occurred on the composite surfaces.
