STRATEGIESSo desperate are some schools that they are willing to operate at losses just to keep their learners from leaving.School managements have designed pro-learner programmes, a strategy that has blown hot and cold working in some cases and backfiring in others.
Engineers typically manipulate the strength of metal through techniques such as cold working or annealing, which exert their effects through small, yet important, structural irregularities called dislocations.
It must be realized that annealing involves recrystallization in which a combination of cold working and subsequent heating causes new stress-free crystals in a matrix which is itself stress free.
Exploring internal and residual stress in materials, 46 papers cover diffraction methods; mechanical relaxation methods; acoustic and electromagnetic methods; composites, nanostructures, and microstructures; films, coatings, and oxides; cold working and machining; heat treatments and phase transformations; welding, fatigue, and fracture; and stresses in additive manufacturing.
"The most important lesson I learned from The Studio at CMOG is the indispensability of cold working in glassmaking," she said.
Over past decades, many studies were dedicated to material flow, dislocation density, residual stress, and cold working hardening during HSCRB process.
Excessive cold working however, may result in an increase in the dislocation density of a metal to as high as 1012 cm square, thus significantly reducing ductility and increasing the likelihood of a brittle failure.16 This happens because as dislocation density increases, due to applied stresses above the yield point, it becomes increasingly difficult for the dislocations to move because their strain fields interact with each other.
Its ultra-lightweight beryllium mirror is more sensitive and six times bigger than Hubble's, and it will operate further away from Earth to maintain an extremely cold working temperature.
To know the extent of cold working, microhardness map of the local area were acquired.
It is a cold working process in which the surface of the component being processed is bombarded with small spherical media.
