Question: Conversely, most heat-treatable alloys are precipitation hardening alloys, which produce the opposite effects that steel does. When heated to form a solution and then cooled quickly, these alloys become much softer than normal, during the diffusionless transformation, and then harden as they age. The solutes in these alloys will precipitate over time, forming intermetallic phases, which are difficult to discern from the base metal. Unlike steel, in which the solid solution separates to form different crystal phases, precipitation hardening alloys separate to form different phases within the same crystal. These intermetallic alloys appear homogeneous in crystal structure, but tend to behave heterogeneous, becoming hard and somewhat brittle.
Try to answer this question if possible: What type of alloys become soft and brittle?
Answer: unanswerable
Question: An alloy is a mixture of either pure or fairly pure chemical elements, which forms an impure substance (admixture) that retains the characteristics of a metal. An alloy is distinct from an impure metal, such as wrought iron, in that, with an alloy, the added impurities are usually desirable and will typically have some useful benefit. Alloys are made by mixing two or more elements; at least one of which being a metal. This is usually called the primary metal or the base metal, and the name of this metal may also be the name of the alloy. The other constituents may or may not be metals but, when mixed with the molten base, they will be soluble, dissolving into the mixture.

Question: In the Middle Ages, Virgil's reputation was such that it inspired legends associating him with magic and prophecy. From at least the 3rd century, Christian thinkers interpreted Eclogues 4, which describes the birth of a boy ushering in a golden age, as a prediction of Jesus' birth. As such, Virgil came to be seen on a similar level as the Hebrew prophets of the Bible as one who had heralded Christianity.
Try to answer this question if possible: Which of Virgil's works was said by some to have predicted Jesus' birth?
Answer: Eclogues 4
Question: Himachal is extremely rich in hydro electric resources. The state has about 25% of the national potential in this respect. It has been estimated that about 20,300MW of hydro electric power can be generated in the State by constructing various major, medium, small and mini/micro hydel projects on the five river basins. The state is also the first state in India to achieve the goal of having a bank account for every family.[citation needed] As per the current prices, the total GDP was estimated at 254 billion as against 230 billion in the year 200405, showing an increase of 10.5%. The recent years witnessed quick establishment of International Entrepreneurship. Luxury hotels, food and franchisees of recognised brands e.g. Mc Donalds, KFC and Pizza hut have rapidly spread.
Try to answer this question if possible: What is the increase of franchisees of recognised brands estimated to be in billions?
