It appears to me that I shall do only what I have a right to do, if I close my address with the following verses:. Let not Cato enter my theatre or, if he do enter, let him look on. Epigrams are written for those who are accustomed to be spectators at the games of Flora. If any assumes to be so scrupulously nice, however, that it is not allowable to address him, in a single page, in plain language, he may confine himself to this address, or rather to the title of the book.

Let the ill-natured interpreter, too, keep himself from meddling with the simple meaning of my jests, and not write my epigrams for me.1 He acted honourably who exercises perverse ingenuity on another man's book: For the free plainness of expression, that is, for the language of epigram, I would apologize, if I were introducing the practice but it is thus that Catullus writes, and Marsus, and Pedo, and Getulicus, and every one whose writings are read through. For me let fame be held in less estimation, and let such talent be the last thing commended in me. A fast cooled billet is identified to have fully solutionized microstructure but requires higher extrusion pressure and is sensitive to preheating rate, while a slow cooled billet is easier to extrude but is not sufficiently solutionized after extrusion.I trust that, in these little books of mine, I have observed such self-control, that whoever forms a fair judgment from his own' mind can make no complaint of them, since they indulge their sportive fancies without violating the respect due even to persons of the humblest station a respect which was so far disregarded by the authors of antiquity, that they made free use, not only of real, but of great names. However, re-precipitation of Mg2Si is observed upon reheating to 450? and dissolution is observed at 500? and 550?. The hardness at room temperature and the flow stress at preheating temperature (450?) and real extrusion temperatures (500-550?) also generally decrease with a slower cooling rate. The homogenized microstructures from specimens exhibit an increase in both amount and size of Mg2Si particles with a decreasing cooling rate. then cooled by 3 different cooling rates: water quenching, air cooling and furnace cooling. The specimens were soaked at 580? for 8 hours, and. In order to optimize the homogenization practice for the extrusion process, the influence of different cooling rates from soaking temperature during homogenization was investigated for an AA6005 alloy. The extrusion behavior and mechanical properties of aluminum alloys are very sensitive to the microstructure of the billets after homogenization. Such adhesion characteristics enhance the transference of the early cracks nucleated towards the substrate steel, a belief that is supported by the analysis of the fracture surfaces of the samples tested at different stress levels. From the microscopic point of view, it has been observed that the fatigue fracture of the substrate-coating composite initiates in the deposit and that it remains well adhered to the substrate during fatigue testing since interfacial cracks have been very rarely observed. Also, the fatigue limit can be reduced between 28.3–50.5% depending upon the condition of the coating.
Thus, it has been shown that the fatigue life of the steel substrate can be reduced up to 94% in the as-deposited condition and up to 99.1% in the as-deposited and PHT condition. The Basquin parameters of the materials tested under different conditions have been determined and used to compute the reduction in fatigue life. It has been determined that both the fatigue life and fatigue limit of the coated substrate are substantially reduced, in comparison with the uncoated material, and that such a reduction is significantly higher if the deposit is in the PHT condition. and post-heat treated (PHT) at 698 K for 1 h, a condition in which the maximum hardness of the deposit was observed.
The evaluation of the fatigue properties of the coated material was conducted in two different conditions: (a) as-deposited and (b) deposited. Such an EN deposit had a P content of approximately 10 wt.% and a thickness of approximately 18 μm. The fatigue properties of a quenched and tempered (Q&T) 4340 (NiCrMo) steel coated with a commercial electroless Ni-P (EN) deposit, has been investigated.
