Foreign atoms lowers the recrystallization rates.

Foreign atoms lowers the recrystallization rates. Correct Answer True

When a foreign atom migrates to a grain boundary, both its elastic field, as well as that of the boundary, are lowered. In recrystallization, grain-boundary motion occurs as the nuclei form and grow. The presence of foreign atoms in atmospheres associated with these boundaries strongly retards their motion and therefore lowers the recrystallization rates.

Given below are four jumbled sentences. Select the option that gives their correct order. Interest rates, in turn, are a crucial determinant of how much firms and consumers want to spend. Conversely, a consumer may be lured into buying a new home if interest rates are low and mortgage payments are therefore more affordable. A firm faced with high-interest rates may decide to postpone building a new factory because the cost of borrowing is so high. The Federal Reserve System strongly influences the size and growth rate of the money stock, and thus the level of interest rates in the economy.
After GST and demonetisation, rising interest rates are set to hurt SMEs. Interest rates for loans against property (LAP) extended to small and medium sized enterprises (SMEs) are set to rise in the coming months of 2018 ‘ Rising interest rates, in addition to the muted operating environment for small businesses in India, will lead to an increase in delinquencies on LAP extended to SMEs’. The introduction of the goods and services tax (GST) in July 2017 and the government's demonetization policy have placed stress on the SME sector, which rising interest rates will exacerbate.
