“…Well documented data is available on the microstructure and mechanical properties of P-22 steel in its initial, preservice condition. [7][8][9] However, information about its postservice properties is quite limited. 10,11 Liaw et al studied the elevated temperature fracture toughness of P-22 steel in four locations: in welds; at the interface between welds and the unmelted steel; in the heat affected zone (HAZ); and in base metal after 22 years service.…”

Extensive service at 540uC led to changes in the composition, morphology, size, and distribution of the original carbides that were present in the pre-service steel. This service did not seem to introduce weakening voids along grain boundaries. At low creep stress levels the stress versus Larson-Miller parameter (LMP) curve of the postservice steel indicates better performance than the lower bound of the pre-service steel. The opposite performance was found at high creep stress levels. The service led to only a slight reduction in fracture toughness of the steel. Exposure to post-service accelerated creep tests led to further gradual reduction in fracture toughness. The reductions in fracture toughness were proportional to the creep strain and duration. The formation of spherical carbides during the accelerated creep tests promoted void formation during the fracture process and thus contributed to the observed additional reduction in fracture toughness.

“…The pin on disc unidirectional dry sliding wear test was performed on Ducom Tribometer. Samples were extracted from NZ (figure 2) for the test and prepared according to ASTM G99-17 standard [35]. Due to insufficient height, a specially designed pin holder was fabricated to hold the pin during wear testing.…”

Despite excellent properties of aluminium silicon (Al-Si) alloys in several aircraft and automotive applications, its usage is limited because near net shape casting of Al-Si alloys may cause several defects like surface pinholes and grooves. Fabrication of components and then welding them via fusion-based welding processes imposes issues like porosity and slag inclusions which may severely degrades its properties. Thus in present study, friction stir welding (FSW) was employed for welding of hypereutectic Al-Si cast alloy. The nugget zone (NZ) of welded alloy and its as-cast counterparts were characterized for their performance in terms of mechanical and tribological behaviour. The results depicted fragmentation of α-Al dendrites, refinement and redistribution of acicular Si particles as a result of stirring with high strain rate, and improvement in mechanical properties such as ultimate tensile strength, yield strength, ductility, hardness and wear resistance as compared to as-cast alloy. It is also shown that disparate wear mechanisms occured in friction stir welded (FSWed) and as-cast alloys. A sizeable amount of adhesion with plastic deformation and delamination pits were observed for as-cast alloy, while the dominant mechanism in FSWed alloy was peeling with little adhesion.

There is an increasing interest in biodegradable materials, such as magnesium, for orthopedic implants. This is driven by their potential to address challenges like stress shielding and the need for secondary removal surgery. In this study, biodegradable magnesium alloys were produced using the Vacuum Induction Casting technique. The impact of micro-alloying Zn and Ca in Mg-xZn-0.2Ca (x= 0.1, 0.2, 0.3, and 0.4 wt%) alloys on corrosion resistance, cytocompatibility, and early-stage inflammatory response was investigated. XRD and SEM-EDS analysis confirmed the presence of Ca2Mg6Zn3 secondary phases in all alloys. The Mg-0.3Zn-0.2Ca alloy exhibited the lowest corrosion rate and an elastic modulus of 33.7 GPa, resembling that of natural bone. Electrochemical measurements indicated a correlation between grain size and secondary phase volume fraction in explaining corrosion behaviour. In vitro degradation in simulated body fluid (SBF) for 21 days showed hydroxyapatite formation on alloy surfaces, aligning with electrochemical studies. In vitro cytotoxicity tests demonstrated the cytocompatibility of all alloys, with Mg-0.3Zn-0.2Ca having the highest cell viability over a 6-day cell culture. Investigation into the inflammatory response with RAW-Blue macrophages revealed the anti-inflammatory properties of Mg-0.3Zn-0.2Ca alloys. Micro-alloying with 0.3 wt% Zn and 0.2 wt% Ca enhanced mechanical properties, corrosion resistance, cytocompatibility, and immunomodulatory properties. This positions the Mg-0.3Zn-0.2Ca alloy as a promising biodegradable implant for bone fixation applications.
