FLASH is an electric field-assisted sintering technique recently proposed to densify materials in a more sustainable, energy reductive and cost-effective way than conventional sintering (CS). FLASH sintering promotes the densification of materials by using a combination of temperature and electric field. The use of electric field allows a decrease in the sintering temperature, and as important as well, in the sintering cycle duration. The advantages of FLASH, when compared with other field-assisted techniques, are: low investment, no need for specific atmosphere and dies, and specimen shape versatility.
