RESUMO O artigo explora e discute as análises do “Manifesto para não ser lido”, texto inaugural da revista Joaquim, criada pelo escritor curitibano Dalton Trevisan em 1946. Desde o seu surgimento, a revista é vinculada pela crítica literária à herança da vanguarda modernista que tem como referência a Semana de 1922. Embora também seja vinculado a essa tradição, o conjunto das evidências analisadas sobre o Manifesto possibilita associar Erasmo Pilotto, o responsável por sua elaboração, ao modernismo de tradição simbolista. As divergências entre os membros da revista, em relação à continuidade ou à ruptura com a tradição, oferecem uma perspectiva privilegiada sobre os debates travados acerca do lugar que Curitiba ocupou no cenário modernista brasileiro.

ABSTRACT The article explores and discusses the analyses of “Manifesto para não ser lido” (Manifesto not to be read), the inaugural text of Joaquim magazine, created in 1946 by the Curitiba writer Dalton Trevisan. Since its inception, the magazine has been associated by literary critics with the heritage of the modernist avant-garde that has the Semana de 1922 as its benchmark. Although it is also linked to this tradition, the evidence analyzed on the Manifesto allows us to associate Erasmo Pilotto, who was responsible for its drafting, with Modernism in the Symbolist tradition. The divergences between the editors of the magazine, in regard to continuity or rupture with tradition, offer a privileged perspective on the debates held about the place Curitiba occupied on the Brazilian modernist scene.

Aluminum alloys of the ANSI series 319 present Si and Cu as the main alloying elements and the mechanical strength of these alloys can be improved by the precipitation of the metastable Al2Cu phase during the ageing heat treatment. In this paper, the Al-5.5wt.%Si-3wt.%Cu alloy was elaborated and solidified in a water-cooled horizontal directional solidification device. The as-cast ingot was subjected to the precipitation hardening heat treatment (T6 heat treatment), which consisted of: solution for 5 h at 490°C±2°C, followed by quenching in water at 60°C±2°C and ageing for 3 h at 155°C±2°C, and cooling-air. Secondary dendrite arm spacing (λ2) measurements were carried out before and after T6 heat treatment. The mechanical strength of the alloy was investigated by the microhardness test. It has been found that the heat treatment did not influence the λ2 values, however, highest HV values have been observed for the heat-treated samples.
