Metal foam can be produced using metal injection moulding with powder space holder. In this study, the effects of volume fraction of spacer holder on the foam properties were studied. Spherical poly (methyl methacrylate) (PMMA) particles were used as a space holder material. The 30% volume fraction of stainless steel 316L powder was mixed with varied volume fractions of binder and PMMA. There were five volume fractions of PMMA, namely 30% to 50%, with an increment of 5%. The results showed that the volume fraction of PMMA affected the properties. As the volume fraction of PMMA increased, the number of …
Study Of Covering Conditions For Sintering Of Metal Injection Moulded Commercially Pure Titanium, N Muenya, A Manonukul
Study Of Covering Conditions For Sintering Of Metal Injection Moulded Commercially Pure Titanium, N Muenya, A Manonukul
Journal of Metals, Materials and Minerals
In metal injection moulding process, sintering for some specific materials is different from general materials. Titanium is a material that is not easy to sinter because it is a very reactive metal at high temperature. The high quality of the titanium component is difficult to control, especially so in point of the levels of carbon and oxygen, which have large effects on the mechanical properties. Commercially pure titanium was injected, debinded and sintered at 1150°C and 1250°C in high vacuum without a cover, and with a quartz cover, a mullite cover and an alumina cover, respectively. From the physical and …
