The precipitates at grain bound.ry in a d.rectionally solid.fied.Ni base superalloy after heat treatment, aging at 975℃, and.creep rupture test have been characterized. Besid.s the primary MC carbid.s and.fine particles of u phase, the Re-containing M23C6 was observed. The precipitation kinetics revealed.that the formation of M23C6 was associated.with the d.ssolution of u phase and.MC carbid.s. TEM image shows that the continuous precipitation of M23C6 particles effectively hind.rs the d.slocation movement and.strengthens the grain bound.ries. The high strength of the alloy suggests that M23C6 carbid.s are beneficial to the properties although Re as an important matrix strengthening element was consumed.

Materials that und.rgo a reversible change of crystal structure through martensitic transformation （MT） possess unusual functionalities includ.ng shape memory, superelasticity, and.low/negative thermal ex- pansion. These properties have many ad.anced.applications, such as actuators, sensors, and.energy conversion, but are limited.typically in a narrow temperature range of tens of Kelvin. Here we report that, by creating a nano-scale concentration mod.lation via phase separation, the MT can be rend.red.continuous by an in-situ elastic confinement mechanism. Through a mod.l titanium alloy, we d.mon- strate that the elastically confined.continuous MT has unpreced.nted.properties, such as superelasticity from below 4.2 K to 500 K, fully tunable and.stable thermal expansion, from positive, through zero, to negative, from below 4.2 K to 573 K, and.high strength-to-mod.lus ratio across a wid. temperature range. The elastic tuning on the MT, together with a significant extension of the crystal stability limit, provid.s new opportunities to explore ad.anced.materials.

The warm powd.r compaction process is simulated.by the finite element analysis software, MSCJMARC. The thermal mechanically coupled.analysis method.is applied.on the basis of the upd.ted.Lagrangian Method. to simulate the warm powd.r compaction process. The warm powd.r compaction process is simulated. and.the influence of friction cond.tion and.pressing styles are researched.on the d.nsity of powd.r green and.the mechanics behavior at certain temperature. The results ind.cate that for cylind.ical compacts, with the improvement of the friction cond.tion, the uniformity of d.stribution of green relative d.nsity is largely improved. the pressing force and.stress d.crease, and.the nonconforming pressing processes influence the d.stribution of green d.nsity to some d.gree. The status of stress d.stribution of the process that punches firstly press and.d.e finally press is d.fferent from the other three processes, and.presents the figure of ＇flume ＇.
