The authors point out the need for more concrete data concerning the physical properties of bronze alloys and present an extensive chart covering the results of actual tests on a large range of cast bronze alloys. The influence of the method of making the test-specimen is discussed and it is hinted that new evidence concerning the proper interpreting of the true proportional limit is available.
A very extensive set of microphotographs illustrates the variety of structures existing in the ordinary and in some unusual bronze alloys.
