    Boron Steels

    A small amount of boron (0'0005 per cent minimum ) is successfully used in the United States as a replacement of appreciable quantities of nickel, chromium and moly-bdenum in structural low-alloy steels. The standard AISI grades are designed to replace conventional alloy steels of equivalent hardenability. The boron steels are norma- lly manufactured by the basic open-hearth process, although the basic electric furnace process is also used . Special equipment is not required in their manufacture and fabrication , but certain precautions are essential in making the boron addition and fini- shing the heats. The production of boron steels attained a maximum of about 0.7 million tons in 1952 and thereaft -er decreased to about 0.5 and 0.25 million tons in 1953 and 1954 respectively. Examples are given to show the general influence of boron on hardenability and mechanical properties of selected steels. A review is made of the literature on the mechanism of boron in increasing hardenability and a summary is presented of known facts on the behaciour of boron in iron and steel

    Research on Light Metals in the Metallurgy Division, National Bureau of Standards

    THE Metallurgy Division of the National Bureau of Standards has accelerated its research programme on metals in order to meet the increased demand for materi-als with improved and special properties so essential for continuing the technological advances of the space arse. Much of the work is designed to furnish basic information on metals and alloys in terms of their structures. Studies are being conducted on problems related to creep, fatigue, corrosion , metal physics , preparation of extremely pure metals and other related fields . Some of' the emphasis of the prograninie is being placed on evaluating specific properties of aluminium, titanium , magnesium, and their alloys

    The Impact of Liability for Enhanced Injury

    Get PDF
    The author discusses the recent imposition of a duty on automobile manufacturers to design a product that is crashworthy. He concludes that the courts will use a balancing test to determine the scope of that duty, and discusses the application of this test. Various attendant problems, such as the seat belt defense and the relevance of uniform federal safety standards, are also considered

    Product Liability in Maryland Revisited

    Get PDF
    The author discusses and compares the various theories of recovery available in a product liability case. He concludes that merger of the various theories into a single basic product cause of action might be procedurally beneficial. Various defenses available in product litigation, as well as procedures for invoking indemnity and contribution, are also discussed
