Metallographic Observation to Determine a Low-content Gold Alloy Castability

Low gold-content dental alloys nowadays represent viable alternatives to high nobility alloys. The casting techniques and equipment used for low-gold content alloys are similar to those used for conventional gold alloys. This, coupled with their acceptable properties, good clinical performance and lower cost, has lead to their widespread use. The alloy performance in the dental laboratory is an...

Metallographic techniques for the determination of the austenite grain size in medium-carbon microalloyed steels

Different techniques have been investigated to seek the best procedure to reveal the prior-austenite grain boundaries in three medium-carbon microalloyed steels. This study has been carried out over a wide range of temperatures (950–1250 C) and it has been found that thermal etching (TE) is the best technique to reveal the prior-austenite grain boundaries in these steels.

Graphene nanocomposite coatings for protecting low-alloy steels from corrosion

facturing methods. Graphene nanocomposite coatings for protecting lowalloy steels from corrosion A ceramic engineer or scientist unfortunately must admit that there is an unwelcome member of the family among us—iron oxide, or rust. This unpleasant family member is disruptive at best. More often it is destructive, nearly impossible to control, and a consumer of resources that are devoted to it i...
