How to mix two or more materials with different melting point for metal composites. What is the process?
I am on study a material that can replace cast iron for cylinder block. As we know cast iron have a high strength material but heavy. So i want to change the material by mix 2 type of material. The problem is both material have 2 different melting point. I still don't know what is the best process to mixing 2 material with different melting point. Anyone can help?

Hi,
Brass is made using Zinc & Copper. Zinc has melting point 419 deg C and Copper melts at 1090 deg C. The result of the two metals brass melts are 900 to 950 deg C.
I think, it is not a problem if two dissimilar metals have different melting point.
The only care is that, the metal having lower melting point should not burn/oxidize.
When course mixture of two dissimilar metals is heated, then the process of combining may start after melting of one; depending on how the metals react with each other. In this process, the molten metal becomes richer with the guest metal and slowly become one solution.
For more details; see the Wikipedia page on the eutectic system.

Hello Samad Jamaludin,
Process is a specific Mogul is zhazhno when you add a second material into the melt. Because Toi can was evaporated or burned or remain dissolved in the melt.
Prodostavyam your materials that you can pogotvish well on this theme.

if you are thinking of MMCs, then there are processes such as stir casting. The reinforcements do not melt during preparations, rather they need to remain unaffected while being mixed into the metal matrix. There is plenty of literature on this. You may also refer to the important papers on available on website of Duralcan.

Residual welding stresses are a key parameter which needs to be controlled in order to minimize failures at the weld site.
The three main observed sources of stress are contraction stress, stress due to higher surface cooling and stress due to phase transformation.

This study was aimed at the rapid development of the current design field, and the theory and concept of our country were still relatively backward. All of these phenomena had caused the waste of resources, and it also resulted in the loss of the cultural connotation in design. Therefore, in view of this situation, in this paper the application of...
This chapter defines ‘design’ as a term, the many forms and disciplines of design (e.g. architectural design, industrial design, graphic design, etc.), and how these disciplines contribute to health and medicine. It discusses the increasing prominence of the term as a verb (i.e., as a process), along with its more traditional use as a noun (i.e., d...
