A method for measuring the spark-shower radiance of metals when abraded on an abrasive grinding wheel was developed for evaluating their sparking tendency. One hundred metals were tested and rated relative to commercially pure iron. The radiance was measured in units of energy per solid angle per area of the detector. The metals tested included elemental metals, iron binary and ternary alloys, iron-carbon ternary alloys, commercial steels, nonferrous alloys, and a few hard-metal compounds. Some alloys were synthesized, others were obtained commercially. Alloys which possessed good strength properties were emphasized for selection. The results indicate that the spark-shower radiance of plain carbon steels and carbon alloy steels was greater than for pure iron. Certain elements, particularly vanadium and chromium, reduced the sparking tendency of iron. Stainless steels and particularly nickel alloys displayed low spark-shower radiance. Some metallic elements had much lower radiance than iron, others much greater. Plain-carbon steels, heat treated to a variety of hardnesses, gave radiance values which gen erally increased with increasing carbon content and hardness, but showed a decreasing radiance trend at high levels of carbon and hardness.

Now major motion picture starring Ryan Gosling (La La Land) and Rachel McAdams (The Time Traveller's Wife) 'When it comes to tales about love, Nicholas Sparks is one of the undisputed kings' Heat How far can love endure? Noah Calhoun has just returned from World War Two. Attempting to escape the ghosts of battle, he tries to concentrate on restoring an old plantation home to its former glory. And yet he is haunted by images of the beautiful girl he met there fourteen years before, a girl who captured his heart like no other. But when these distant memories begin to slide into reality, the passion that had lain still is ignited once more. Though so much is in their way, the miraculous force of their love refuses to fade. Praise for Nicholas Sparks: 'A fiercely romantic and touching tale' Heat 'An A-grade romantic read' OK! 'Pulls at the heartstrings' Sunday Times 'An absorbing page-turner' Daily Mail 'This one won't leave a dry eye' Daily Mirror
