Quiz on Grain Test Welcome to your Quiz on Grain Test 1. Metallurgical Tests confirm that the chemical requirements of pipe are as per the material standard. True False 2. The grain size of a metal or single phase alloy is an estimate of the average grain diameter True False 3. grain Size is usually expressed in meters True False 4. As the average grain size decreases, the metal becomes stronger True False 5. Factors which influence the grain size are: Alloy chemistry Cold work done to the material Annealing process All of the above 6. Certain elements, such as titanium and niobium, create resistance towards grain growth in stainless steels True False 7. Grain growth is due to an alteration of the internal energy of the molecular structure of a given metal, ceramic or mineral True False 8. Cold work results in finer grains True False 9. A longer time at the target temperature in annealing promotes grain growth. True False 10. The common industry standards are ASTM E112 ISO 643:2012 Both of the Above 1 out of 5
