Abstract EASTERN STAINLESS TYPE 309S is a heat-resisting grade of stainless steel. Because of its high alloy content, it resists scaling up to 2000 F. It also has good tensile and creep properties and elevated temperatures. Type 309S has good ductility and malleability; therefore, difficult shapes and structures can be fabricated easily and it can be machined readily. It can be welded easily and gives strong, ductile welds. Some of its many applications are annealing boxes, boiler baffles, dryers, furnace parts, heat exchangers and oil-refining equipment. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-441.

Exhaust Systems

Titanium and its alloys have been applied to motorcycles and automobiles in order to reduce the weight of their component parts. In recent years, titanium exhaust systems, engine valves and connecting rods have been widely applied mainly to sports type or large motorcycles. In addition to Ti-6Al-4V, Ti-Al-Fe alloys which utilize Fe as an inexpensive and a common alloying element are used for engine valves and connecting rods. In exhaust systems, such as mufflers, at first, Gr.2 commercially pure titanium sheets have been mainly used because of their high cold formability. Furthermore, several titanium alloys to which Cu, Al, Si and Nb are added have been actively developed in order to improve strength, creep properties, oxidation resistance and so on at elevated temperatures, as service temperature becomes higher. Also, due to the development of processing technologies, the same methods and processes that are used for manufacturing steel parts have been applied to titanium ones, and the application of titanium has recently been expanded to fracture-split connecting rods and fuel tanks. Newly, titanium foil has been adopted as a separator of PEFC used in fuel cell vehicles from the viewpoints of excellent corrosion resistance and cold formability. As mentioned above, in this presentation, the technical contents of titanium products and parts developed for motorcycles and automobiles are reviewed.

Cast Microstructure

Microstructures and creep properties of AM80 alloy with calcium and strontium additions have been investigated by using OM, X-ray diffraction, SEM and creep tests. The results indicate that the as-cast microstructure of the AM80 alloy consists of the α-Mg matrix, bones-shaped Mg17Al12 and lamellar second precipitation phase at grain boundaries. Calcium and strontium can refine the grain size and the secondary phases. Calcium addition results in the formation of a fishbone Al2Ca eutectic phase in AM80 alloy. With the increase of calcium, reticular Al2Ca phase distribute at the grain boundaries. The creep resistance of the AM80 alloy is significantly improved by a small amount of strontium and calcium addition due to the formation of a grain boundary network consisting of the high melting point Al2Ca phase. Microstructure observations performed on the sample after creep testing reveal that the phase is distorted during creep, reflecting its formation in the as-cast microstructure is unbeneficial to creep properties of the AM80 alloy. The creep resistance of the alloy at elevated temperatures was remarkably increased when calcium was added combined with strontium. The highest creep resistance was obtained from the alloy with xSr and y3Ca addition and its steady state creep rate reached as low as 3.941×10-8s-1, one order of magnitude lower than that of alloy AM80 without strontium and calcium additions.

Compression Deformation

In this research, the compression deformation were investigated under different elevated temperatures and strain rates, in order to obtain the creep constitutive equation. The effects of aperture load and pore shape on the compression properties of porous Cu alloys were studied by simulating the creep compression deformation at elevated temperature in ANSYS software. Pore size, pore shape and load are the main factors on the high temperature compression creep properties in porous Cu alloys. Samples with larger pore size, higher load and temperature showed inferior compression creep resistance such as bigger creep deformation, faster creep rates, and more unstable creep deformation. Stress concentrations generating around the edge in the wall of the pore were observed. Otherwise, the shape of pore has a severe influence on the structure properties of the material, i.e. every increase of pore edge corresponds to a decrease of stability in structure.
