“…As seen, the as-sintered sample has the coarse lamellar microstructure that is typical of PM α + β Ti alloys (Figure 27(a)). However, after forging, the microstructure is significantly refined in all areas of the connecting rod (Figure 27(b)), with the finest microstructure found in the shank (Figure 27(c)) [247]. Similar results were observed in a study on PM Ti-10V-2Fe-3V sintered at 1200°C followed by forging and heat treatment [251].…”

Powder metallurgy (PM) of titanium is a potentially cost-effective alternative to conventional wrought titanium. This article examines both traditional and emerging technologies, including the production of powder, and the sintering, microstructure, and mechanical properties of PM Ti. The production methods of powder are classified into two categories: (1) powder that is produced as the product of extractive metallurgy processes, and (2) powder that is made from Ti sponge, ingot, mill products, or scrap. A new hydrogen-assisted magnesium reduction (HAMR) process is also discussed. The mechanical properties of Ti-6Al-4V produced using various PM processes are analyzed based on their dependence on unique microstructural features, oxygen content, porosity, and grain size. In particular, the fatigue properties of PM Ti-6Al-4V are examined as functions of microstructure. A hydrogen-enabled approach for microstructural engineering that can be used to produce PM Ti with wroughtlike microstructure and properties is also presented.

“…The function of the connecting rod is to transmit the thrust of the piston to the crankshaft and translate the transverse motion to rotational motion. It should be strong enough to remain rigid under loading, and also be light enough to reduce the inertia forces, which are produced when the rod and piston stop, change directions and start again at the end of each stroke [1].…”

The main microstructure of the crackable C70S6 steel is pearlite (%90 of the structure is about pearlite). Changing the microstructure by various heat treatment applications such as hardening&quenching, annealing, tempering can be economic and technologic alternatives to the use of crackable C70S6 steel. In this study, the microstructure and the metallography of the crackable C70S6 steel is examined by various heat treatment applications. Besides this, some fracture experiments has been carried out for each heat treatment application. Finally, it has been seen that tempered martensite structure can be an important alternative to the pearlitic crackable C70S6 connecting rods.

“…Under vacuum pressure, the melt solid lubricant is immersed in the micro-pore matrix. Under the action of high temperature and friction heat, the solid lubricant is precipitated out to the friction interface along the micro-pore structure [1]. The material has good mechanical properties and selflubricating properties under special working conditions such as high temperature and high pressure, and is widely used in aerospace, electronic machinery and other industries.…”

Metal ceramic preforms were fabricated by vacuum sintering method in this work. Ti–Fe–Cr–W–Mo–V powder was used as the basic material, TiH2 and CaCO3 were used as the composite pore-forming material and Al2O3 was used as dispersal particles. The microstructure and the worn surface morphology of the preforms and the composites were analyzed using scanning electron microscope (SEM) and energy dispersive spectrometer (EDS). The experimental results showed that when the micro-pore shapes are circular and quadrilateral respectively, with the increasing load, the Mises equivalent stress distribution generated by the single cell model is quite different, but it has symmetry, and the maximum stress appears around the interpenetrating micro-pore. Using FeCrWMoV alloy powder as the metal phase and TiC powder as the ceramic phase, the micro-porous matrix was prepared by powder metallurgy sintering with the addition of a certain volume fraction of compound pore-making agent.
