Continuous wave (CW) laser was used to melt micrometer sized powders mixed with various nanoparticles (NPs) such as titanium NPs. To create “nano-liquid” during the laser melting of powders, NPs of high melting point are mixed with powders so that the NPs are kept in solid phase while the lower melting point powder elements become liquid. During this short period time, the laser melted liquid can be viewed as nanoliquids. Nanoliquids have been known as a medium of excellent heat transfer so commercial nanoliquids are available such as engine coolant and liquid for drilling oil wells. We discuss the laser melting of powders such as SmCo5 with titanium NPs including their crystalline structure and hardness.
