“…The TRIP780 steel analyzed presented a microstructure consisting of ferrite, martensite, bainite and retained austenite, a result according to the FCA MS.50002 standard [15]. V. Paranthaman studied the TRIP780 steel and also found the microstructure composed of multiphase bainite, ferrite, retained austenite and martensite [19]. The microstructures of the analyzed steels are in accordance with their respective specifications.…”

In this study, a methodology was successfully developed and validated to evaluate the behavior of spot welded joints of DP780, TRIP780 and DC04 steels in high cycle fatigue. Test specimens were made with three spot welds and Wohler curves were developed using the uniaxial tensile/traction load adopting the Owen R90C90 method. The spot welds showed an increase in fatigue life and a reduction in the maximum load, similar to steels. The influence of mechanical strength and material thickness tested and the types of fractures that occurred were compared. In low cycle regions, spot welds showed greater dispersion at maximum loading, between the different materials, and in higher cycle regions, this dispersion was reduced. The results obtained by adopting this method using three spot welds showed greater repeatability and less variation between the specimens of the same material. This developed method can be used with increased reliability to develop automotive bodies and spot welded components.

“…In addition, the stir-casting machine's stirrer and varied agitation rates effectively combine the base material with reinforced particles (450, 500, 550, and 600 rev/min). A variety of agitation time periods (15,20,25, and 30 minutes) were used to ensure that the composites were thoroughly mixed. Finally, the crucible's molten contents were poured into the dies to produce the desired forms.…”

“…To improve the mechanical characteristics and strength of various alloy materials for reinforcing hare particles, stircasting was heavily utilized. To prepare a composite, stircasting method process parameters play a significant role, with each one having an impact on a different character [25]. Composite characteristics have an impact on the final outcome.…”

Aluminum alloys are currently used in a wide variety of industries, and strong aluminum alloys are required for the creation of new components. As a result, multiple scientists are experimenting with various compositions of hybrid aluminum metal matrix composites. The purpose of this experiment was to generate hybridization on aluminum alloy 7076 using stir-casting and nano zirconium dioxide and BN reinforcements. Taguchi’s approach was used to optimize the stir-casting process criteria in this investigation. The parameters employed in this investigation were agitation speed, agitation time, and temperature. The chosen constraints are the percentage of reinforcement (0–12%), the agitation speed, the agitation time, and the molten state temperature. We used a wear tester and a Vickers hardness tester to determine the wear and microhardness of the produced stir casting materials. By optimizing wear parameters, the least wear rate is determined.

Over the last few years, natural fiber-based hybrid polymers have been widely used to increase the biodegradability and cost-effectiveness of the products in many industrial applications, such as automobile construction industries. Adding filler materials provides enhanced wear properties and thermal behaviors of composites. Kenaf fiber has better strength and stiffness, and it has been used as reinforcement in polymer composites. Silicon carbide as filler material in composites modifies the mechanical properties and thermal behaviors. The present research analyzes the thermal characteristics of silicon carbide/kenaf fiber-reinforced epoxy composites with various weight percentages. Six different composite specimens were fabricated at varying weight percentages of silicon carbide. The specimens were subjected to various thermal tests, such as heat deflection temperature (HDT), coefficient of thermal expansion (CTE), thermal conductivity (TC), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The findings could serve to expand the range of application for SiC/kenaf fiber-reinforced composite, which may have better thermal stability, better performance, and lower thermal expansion than the other regularly used natural fiber-reinforced composites.
