According to this invention, these is provided a device for in-situ microwave casting of metals and alloys comprising a microwave applicator having a cavity to accommodate a mold assembly containing target metal exposed to microwave for the casting thereof. The device involves a microwave casting procedure wherein a metal is melted within a pouring basin according to microwave hybrid heating technique. The mold assembly comprises of a pouring basin which can absorb microwave energy and conventionally heats the metal up to a material specific critical temperature of the metal. Further, microwave absorption dominates heating of the metal. The molten metal gets self-poured into the mold thorough a ceramic sprue. An insulating gasket around the mold assembly can be provided to further enhance the thermal heating efficiency of the system. Thus, the process reduces the risk related to transfer of molten metal in to mold as compared to the prior art.

It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
